Synthesis and properties of castor oil based plasticizers
Plasticizers prepared from vegetable oils mainly include epoxy vegetable oils, 5–8 and epoxidized fatty acid esters. 9 In these types of plasticizers, the presence of the epoxy group makes the plasticizers have a better plasticizing effect on PVC and plays a role as stabilizer. 10 When heated, PVC undergoes autocatalytic dehydrochlorination, whereas the epoxide group can scavenge the
Solutions to Hazardous Plasticizers - Clean Production Action
Solutions to Hazardous Plasticizers. October 01, 2014 Bulletins. The dominant movement in the marketplace is to alternative plasticizers to DEHP and other phthalates. Yet this is the less preferred solution to avoiding PVC and plasticizers altogether. Some recent assessments on alternative materials and plasticizers include:
Study on Cellulose Acetate Butyrate/Plasticizer Systems by
Cellulose acetate butyrate (CAB) is a widely used binder in polymer bonded explosives (PBXs). However, the mechanical properties of PBXs bonded with CAB are usually very poor, which makes the charge edges prone to crack. In the current study, seven plasticizers, including bis (2,2-dinitro propyl) formal/acetal (BDNPF/A or A3, which is 1:1 mixture of the two components), azide-terminated
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.

While less preferable than avoiding PVC and plasticizers altogether, if a company can’t avoid PVC, here are two analyses of alternative plasticizers. The Healthy Building Network (HBN) and Green Chemistry and Commerce Council (GC3) used the GreenScreen (GS) to evaluate alternatives to phthalates in building products (HBN) and DEHP in wire and
- Are plasticizers a health hazard?
- Wiesinger, H.Legacy and Emerging Plasticizers and Stabilizers in PVC Floorings - Rawdata. Mendeley Data2023, DOI: 10.17632/s4g2y7c7c7.1 There is no corresponding record for this reference. Hazardous chemicals in building and construction plastics can lead to health risks due to indoor exposure and may contaminate recycled materials.
- Are plasticizers and stabilizers changing in the PVC industry?
- For example, PVC plastics have been notorious for their extensive use of multiple hazardous ortho -phthalates as plasticizers and cadmium, lead, and tin as stabilizers. Consequently, the use patterns of plasticizers and stabilizers are changing in the PVC industry, shifting from well-known hazardous substances to alternative ones. (11,12)
- What is a stabilizer in PVC plastic?
- Stabilizers are a key central additive in PVC plastic formulations. Flexible PVC materials are built upon liquid mixed metal soaps that are the most commonly used stabilizers.
- What are the best value-added PVC plasticizer options?
- Let’s now turn our attention to three value-added PVC plasticizer options that exceed the emerging requirements of REACH and European Union (EU) regulation. VESTINOL® 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window.
- Are organic heat stabilizers suitable for PVC?
- In recent years, environmentally friendly organic heat stabilizers have been prepared and developed for the heat stability of PVC. Wang et al. [ 8] studied tung-oil-derived imide epoxidized esters as a PVC heat stabilizer.
- Are DBS and DHS a good plasticizer for PVC?
- Where data was available, the results from this study are in good agreement with the experiment; we conclude that DBS and DHS are most promising green plasticizers for PVC, since they have properties comparable to DEHP but not the environmental and toxicity concerns.
